I bought this quite a while ago. I wore it once or twice. I forgot about it and left it stored away. The size is approximate, as I measured it myself: Width: 33 cm Front length: 35 cm Back length: 31 cm 100% cotton Please check the stain in photo 8. The length of the shoulder straps can be adjusted with the buckle in the back. Please understand that this is a used item and has been stored at home.
